<title>Defining a status handler</title>
</head>
<body>

<h2>Defining a status handler</h2>

<p>There are two ways for contributing handlers to the Workbench:</p>
<ol>
	<li>using the <em>org.eclipse.ui.statusHandlers</em> extension
	point, see <a href="ua_statushandling.htm">User assistance and
	status handling</a></li>
	<li>using a custom workbench advisor and overriding its <em>getWorkbenchErrorHandler()</em> method</li>
</ol>


<h3>Contributing a status handler using the custom advisor</h3>

<p>First, a custom workbench advisor for your application has
to be created. In this new custom advisor override <em>getWorkbenchErrorHandler()</em>. 
This will now return the default error handler.</p>
<pre>
   public class CustomWorkbenchAdvisor extends WorkbenchAdvisor {
      public AbstractStatusHandler getWorkbenchErrorHandler() {
         ...
         
         return customStatusHandler;
      }
   }
</pre>


<p>In the custom application use your new advisor when creating the
<code>Workbench</code>.</p>
<pre>
   public class CustomApplication implements IApplication{
      public Object start(IApplicationContext appContext) throws Exception {
         ...
         Display display = createDisplay();
         PlatformUI.createAndRunWorkbench(display, new CustomWorkbenchAdvisor());
         ...
      }

      protected Display createDisplay() {
         return PlatformUI.createDisplay();
      }
   }
</pre>

<p>For details how to run a custom application see the <b><a
	href="../reference/extension-points/org_eclipse_core_runtime_applications.html">
org.eclipse.core.runtime.applications</a></b> extension point documentation.</p>

<p>When the status handling facility is accessed, the facility will
get instance of the handler that is provided by the custom advisor. This handler will be 
used for handling of status or error occurred in the application.</p>
